Manual Instruction Extract: Track Removal

Follow these steps to safely remove the track:

1. Position the machine on a smooth, level surface with enough space for forward and reverse movement.
2. Relieve track tension according to the “Track Tension” section of the manual.
3. Move the machine until the master link is at approximately the 10 o’clock position on the front idle roller.
4. Remove the four nuts and bolts securing the shoe to the link, removing enough shoes for easier access to the lock pin.
5. Ensure track shoes are supported with blocking; once the master pin is removed, the track should not fall.
6. Straighten and remove the lock pin; discard it after removal.
7. Remove the master pin from the master links.
8. Move the machine backward to lay the entire track on the ground, without driving it off the track.
9. Rotate the upper structure to 90 degrees away from the track. Use the bucket and boom to lift the track frame off the track.
10. Position blocking under the frame for stability.
